Now we see the pagan temples not only closed, but razed to the ground, the images broken and swept away, their worship, and even private sacrifice, forbidden under pain of death. From Libanius we may gather something of the desolation which this spread among the pagan peasant-folk. Residing at a distance from the great centres where doctrines were being expounded, they found themselves bereft of the old gods and without knowledge of the new. Their plight is a far more pathetic one than that of the Arians, Manichæans, Donatists, and all other heretics against whom there was a similar enactment. It is now, at this early date, that for the first time we come across the title “Inquisitor of the Faith,” in the first law[3] promulgated to render death the penalty of heresy. It is now that we find the great Augustine of Tagaste--the mightiest genius that the Church has brought forth--denouncing religious liberty with the question, “Quid est enim pejor, mors animæ quam libertas erroris?”[4] and strenuously urging the death of heretics on the ground that it is a merciful measure, since it must result in the saving of others from the damnation consequent upon their being led into error. Similarly he applauded those decrees of death against any one pursuing the polytheism that but a few generations earlier had been the official religion of the Roman Empire. It was Augustine--of whom it has been truly said that “no man since the days of the Apostles has infused into the Church a larger measure of his spirit”--in his enormous fervour, and with the overwhelming arguments inspired by his stupendous intellect, who laid down the principles that governed persecution, and were cited in justification of it for nearly 1,500 years after his day. “He was,” says Lecky, “the most staunch and enthusiastic defender of all those doctrines that grow out of the habits of mind that lead to persecution.”[5] So far, however much persecution may have been inspired by the Church, its actual execution had rested entirely and solely with the civil authorities; and this aloofness, indeed, is urged upon the clergy by St. Augustine. But already before the close of the fourth century we find ecclesiastics themselves directly engaged in causing the death of heretics. Priscillian, a Spanish theologian, was led by St. Paul’s “Know ye not that ye are the temple of God?” to seek to render himself by purity a worthy dwelling. He preached from that text a doctrine of stern asceticism, and forbade the marriage of the clergy. This at the time was optional,[6] and by proclaiming it to be Christ’s law he laid himself open to a charge of heresy. He was accused of magic and licentiousness, excommunicated in 380 and burnt alive, together with several of his companions, by order of two Christian bishops. He has been described as the first martyr burnt by a Spanish Inquisition.[7]
